Actigraphy

Actigraphy is based on small wristwatch-like devices that monitor the intensity of wrist movement, closely approximating whole body movements, for extended periods of time.

Validated computerized algorithms transform raw activity scores into Sleep-Wake scores and allow calculation of sleep variables such as

  • Sleep efficiency
  • Total Sleep Time
  • Total Wake Time
  • Sleep Latency
  • Frequency and duration of nighttime awakenings

As wearing actigraphs day and night for long periods of time is well tolerated, actigraphy is a great monitoring tool within clinical trials. It can record information that is not captured with Polysomnography during a single night in the sleep laboratory and is particularly helpful when it comes to patients with sleep-wake rhythm disorders.

We provide a complete solution for clinical trials with actigraphy:

  • Device rental
  • Data analysis including not only sleep- but also circadian variables
  • Adjustable sleep diary and/or sleep log
